Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology, and in particular to an automatic panel clamping fixture and conveying device. Background Technology

[0002] An H-shaped panel is a component with a specific shape and structure, resembling the letter "H," used in industrial production or specific applications. In practical applications, H-shaped panels are widely used in various fields such as machinery manufacturing, electronic equipment, and furniture production. For example, in air conditioner indoor units, H-shaped panels can be used as a support structure for air vent grilles or decorative panels. Their shape provides a stable frame, ensuring the accuracy of the air vent shape and airflow guidance, while also playing a decorative and aesthetically pleasing role in the overall design, making the indoor unit more visually appealing and harmonious.

[0003] In the production of air conditioners, the handling and assembly of H-shaped panels is a crucial step. Traditional production methods primarily rely on manual labor for moving and assembling these panels, a model with significant drawbacks. First, manual handling is extremely inefficient, severely slowing down the entire production process. Second, the high intensity of manual labor places a heavy physical burden on employees, easily leading to fatigue, injuries, and other health problems, while also increasing the company's human resource management costs. Furthermore, the varying skill levels and carelessness of different workers frequently result in damage to the products during handling. These uncontrollable factors not only lead to product scrap and increased raw material costs but can also cause rework and other delays, further wasting time and money.

[0004] Therefore, it is necessary to improve the existing handling method of H-type panels to overcome the shortcomings of the existing technology. Utility Model Content

[0005] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide an automatic panel gripper that can automatically grip and transport panels, and can hold multiple panels at a time, thereby effectively improving the panel handling efficiency.

[0006] An automatic panel gripper includes:

[0007] The mounting bracket has several clamping components, each including a drive device and a gripper. The drive device is mounted on the mounting bracket, and the gripper is located at the output end of the drive device. The drive device drives the gripper to open and close. The gripper also has a locking position.

[0008] Multiple clamping components on the mounting rack can operate simultaneously, handling multiple panels at a time. Assuming each clamping component has a work cycle of 7 seconds (including clamping and placement time), in batch handling tasks, the handling efficiency can be increased by 6-8 times compared to traditional single-panel handling fixtures, significantly shortening material handling time, accelerating production pace, and reducing production costs. Furthermore, the snap-fit ​​design effectively prevents panel displacement, shaking, and detachment during handling, avoiding panel damage or affecting subsequent processing and assembly accuracy due to improper handling, improving product quality and production qualification rate, and ensuring smooth production processes.

[0009] In a preferred embodiment of this invention, the driving device has two output ends, each of which has a gripper, and the two grippers are arranged opposite to each other; the two output ends drive the two grippers to move closer or further apart.

[0010] The locking position is a locking slot, which is located on the opposite sidewalls of the two grippers.

[0011] In a preferred embodiment of this invention, N slots are provided on the sidewall of the gripper, and the N slots are arranged along the height direction of the sidewall of the gripper; N is a natural number greater than 1.

[0012] The multi-slot design of the grippers allows for a greater number of panels to be handled at once. Compared to traditional single-panel handling fixtures, handling efficiency can be increased many times over, significantly reducing material handling time, accelerating the production process, significantly improving enterprise production efficiency, and enhancing market competitiveness.

[0013] In a preferred embodiment of this invention, a buffer block is provided on the gripper, and the locking position is provided on the buffer block.

[0014] When the cylinder drives the grippers to clamp the panel, the buffer block absorbs part of the clamping force, making the actual clamping force on the panel more even and gentle, avoiding panel deformation, cracking, or internal structural damage due to excessive local force. This is crucial for some panels with brittle materials or complex structures, ensuring the integrity and functionality of the panel during handling.

[0015] In a preferred embodiment of this invention, the mounting bracket is provided with two opposing connecting arms, and each connecting arm is provided with a clamping member.

[0016] In a preferred embodiment of this utility model, the mounting bracket is further provided with a guide rail, which is arranged along the length direction of the connecting arm;

[0017] A slider is provided on the guide rail, and the clamping member is provided on the slider;

[0018] The mounting bracket is also equipped with a drive cylinder for driving the slider.

[0019] The guide rails and slider structure on the mounting bracket, along with the drive cylinder that moves the slider, allow the clamping component to be flexibly adjusted within a certain range. When dealing with panels of different sizes, shapes, or layouts, the drive cylinder can push the slider to ensure the clamping component accurately grips the key parts of the panel, improving the versatility and adaptability of the fixture. For example, when producing various models of electronic device panels, even if the corner positions or dimensions of the panels differ, reliable clamping can be achieved by adjusting the position of the clamping component, reducing the need to change fixtures due to panel differences and improving production efficiency.

[0020] In a preferred embodiment of this invention, a connecting flange is provided in the middle of the mounting bracket, and the connecting flange is provided with multiple mounting holes.

[0021] The second objective of this utility model is to provide a handling device, including a robotic arm, on which an automatic panel gripper as described above is provided.

[0022] In a preferred embodiment of this invention, the automatic panel gripper is equipped with a photoelectric sensor, which is positioned facing the gripper and is electrically connected to the control system of the robotic arm.

[0023] This handling device uses photoelectric sensors to accurately detect the contact and gripping status between the grippers and the panel, promptly identifying whether the panel is correctly held during the gripping process. Compared to relying solely on pressure sensors or manual observation, this multi-sensor collaborative approach further improves the accuracy and reliability of gripping. For example, when handling high-precision electronic panels, it can effectively avoid panel damage or subsequent processing accuracy issues caused by improper gripping, thereby improving product yield.

[0024] The beneficial effects of this utility model are as follows:

[0025] This utility model provides an automatic panel gripper, which includes a mounting frame with several gripping components. Each gripping component includes a drive unit and grippers. The drive unit is mounted on the mounting frame, and the grippers are located at the output end of the drive unit. The drive unit drives the grippers to open and close. The grippers also have locking positions. During use, the gripper is driven by a robot, which lowers the gripper to align the grippers with the edge of the panel. Then, the drive unit activates, pushing the grippers to close, and the locking positions accurately engage the corners of the panel, thus gripping it. The robot then moves to place the panel at the target location. In practical applications, the locking positions on the grippers are custom-designed according to the panel's edge contour, and the drive unit controls the opening and closing of the grippers, ensuring the panel's positional accuracy and stability during gripping. During handling, the panel will not shift, shake, or fall off, avoiding damage to the panel or precision issues in subsequent processing and assembly due to improper handling. Furthermore, the multiple gripping components can simultaneously hold different panels, thereby improving the efficiency of panel gripping and handling.

[0026] This application also provides a conveying device including the above-mentioned automatic panel gripping fixture, which can realize automatic panel conveying, improve panel conveying efficiency, and thereby increase the material flow speed on the production line. Attached Figure Description

[0035] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0036] In the production of air conditioners, the handling and assembly of H-shaped panels is a crucial step. Traditional production methods primarily rely on manual labor for moving and assembling these panels, a model with significant drawbacks. First, manual handling is extremely inefficient, severely slowing down the entire production process. Second, the high intensity of manual labor places a heavy physical burden on employees, easily leading to fatigue, injuries, and other health problems, while also increasing the company's human resource management costs. Furthermore, the varying skill levels and carelessness of different workers frequently result in damage to the products during handling. These uncontrollable factors not only lead to product scrap and increased raw material costs but can also cause rework and other delays, further wasting time and money.

[0037] Based on this, this application provides an automatic panel gripper.

[0038] Example 1

[0039] See Figures 1-6 This embodiment provides an automatic panel gripper, which includes a mounting frame 1. The mounting frame 1 is provided with a plurality of gripping members 2. Each gripping member 2 includes a driving device 22 and a gripper 21. The driving device 22 is mounted on the mounting frame 1, and the gripper 21 is mounted on the output end of the driving device 22. The driving device 22 drives the gripper 21 to open and close. The gripper 21 is also provided with a locking position.

[0040] Specifically, the mounting frame 1 is made of high-strength steel and undergoes precision machining and heat treatment to ensure its excellent rigidity and stability. Even better, the mounting frame 1 can be designed with reinforcing ribs around its perimeter. These ribs are 5mm thick and 20mm high, arranged in a triangular pattern, effectively enhancing the overall rigidity of the mounting frame 1 and enabling it to withstand various external forces and vibrations during handling.

[0041] During use, the clamp is driven by a robot, which lowers the clamp to align the grippers 21 with the edge of the panel. Then, the drive unit 22 activates, pushing the grippers 21 to close, accurately engaging the corners of the panel 100 to grip it. The robot then moves to place the panel at the target location. In practical applications, the engagement points on the grippers 21 are custom-designed according to the panel's edge contour, and the drive unit 22 controls the opening and closing of the grippers 21, ensuring the panel's positional accuracy and stability during clamping. During transport, the panel will not shift, shake, or fall off, avoiding damage to the panel or precision issues in subsequent processing and assembly due to improper handling. Furthermore, multiple grippers 2 can simultaneously hold different panels, thereby improving the efficiency of panel clamping and transport.

[0042] In this embodiment, a specific implementation of the driving device 22 is provided. The driving device 22 is provided with two output terminals, each of which is provided with a gripper 21. The two grippers 21 are arranged opposite to each other; the two output terminals drive the two grippers 21 to move closer or further apart.

[0043] The locking position is a locking slot 211, which is disposed on the opposite sidewalls of the two grippers 21.

[0044] The drive device 22 is a dual-axis cylinder with two opposing piston rods. The ends of the two piston rods can move closer or further apart. Each piston rod end is equipped with a gripper 21, which can drive the two grippers 21 to move closer or further apart. The dual-axis cylinder is model SC100-200, which has good linear motion performance and large output force. The cylinder body is made of high-quality carbon steel, and after quenching and tempering, the hardness reaches HRC40-45, ensuring its strength and wear resistance. The piston and piston rod inside the cylinder are made of 304 stainless steel with chrome plating and a surface finish of Ra0.4μm, reducing motion friction and wear, and improving the cylinder's service life and motion accuracy.

[0045] More specifically, a connecting flange 11 is provided in the middle of the mounting bracket 1, and a plurality of mounting holes 110 are provided on the connecting flange 11.

[0046] The connecting flange 11 is used for connection with the robotic arm, improving the ease of installation of the fixture. The connecting flange 11 is circular, with a diameter of 300 mm and a thickness of 35 mm. The flange is made of forged carbon steel and has undergone normalizing treatment to improve its overall mechanical properties. Twelve mounting holes 110 are evenly distributed along the circumference of the flange. The mounting holes 110 are 20 mm in diameter, with a positional accuracy controlled within ±0.03 mm. They feature a countersunk hole design with a countersunk depth of 15 mm, facilitating the concealment of bolt heads during connection with the robotic arm and preventing interference. The flange surface has been ground to a roughness of Ra0.1 μm, ensuring a tight and smooth connection with the robotic arm.

[0047] Example 2

[0048] This embodiment is an optimization based on embodiment 1.

[0049] See Figures 1-6 In this embodiment, N slots 211 are provided on the side wall of the gripper 21, and the N slots 211 are arranged along the height direction of the side wall of the gripper 21.

[0050] The N slots 211 enable the gripper 21 to hold multiple panels in a single gripping operation, thereby effectively improving the panel handling efficiency.

[0051] In practical applications, assuming N=4, the depth of the slot 211 is 20mm and the width is 10mm, the inner wall is frosted (roughness Ra0.8μm), and the spacing between adjacent slots 211 is set to 25mm based on common panel thickness and stability, which can achieve clamping of multiple panels at one time.

[0052] Efficient material handling reduces manual intervention and lowers labor costs. Shorter production cycles accelerate capital turnover, reduce time costs, give companies a price advantage in market competition, and improve profitability.

[0053] Example 3

[0054] This embodiment is an optimization based on embodiment 2.

[0055] See Figures 1-6 In this embodiment, a buffer block 212 is provided on the gripper 21, and the locking position is provided on the buffer block 212.

[0056] The buffer block 212 can be made of rubber with a Shore hardness of 40-50 HA, providing good elasticity and cushioning performance. The buffer block 212 can be glued to the gripper 21 with strong adhesive to ensure a firm connection. The locking position is set on the buffer block 212, and the shape of the locking groove 211 is adapted to the edge of the panel, which can effectively protect the panel from damage during clamping.

[0057] When the cylinder drives the gripper 21 to clamp the panel, the buffer block 212 can absorb part of the clamping force, making the actual clamping force on the panel more uniform and gentle, and avoiding panel deformation, cracking or internal structural damage due to excessive local force. This is crucial for some panels with brittle materials or complex structures, ensuring the integrity and functionality of the panel during handling.

[0058] Furthermore, because the buffer block 212 reduces the hard impact and friction between the gripper 21 and the panel, it slows down the wear rate of the gripper 21 and extends its service life. At the same time, it also reduces equipment failures and downtime that may be caused by panel damage, improving the stability and reliability of the entire handling system and reducing equipment maintenance costs and production losses.

[0059] In a preferred embodiment, a pressure sensor may also be provided on the buffer block 212. During the clamping process, the control system adjusts the pushing force of the push rod of the drive device 22 in real time according to the pressure information fed back by the pressure sensor, so as to ensure that the gripper 21 can firmly clamp the panel, but will not damage the panel due to excessive pressure.

[0060] Example 4

[0061] This embodiment is an optimization based on embodiment 1.

[0062] See Figures 1-6 In this embodiment, the mounting frame 1 is provided with two opposing connecting arms 12, and each connecting arm 12 is provided with a clamping member 2.

[0063] In this embodiment, the mounting bracket 1 is also provided with a guide rail 3, which is arranged along the length direction of the connecting arm 12;

[0064] The guide rail 3 is provided with a slider 31, and the slider 31 is provided with the clamping member 2;

[0065] The mounting bracket 1 is also equipped with a drive cylinder 4 for driving the slider 31 to move.

[0066] Specifically, the slider 31 is made of high-strength aluminum alloy, and each slider 31 is equipped with a clamping component 2, which is connected by bolts. The connecting bolts are made of high-strength alloy steel grade 8.8, and the tightening torque is 200 N·m to ensure a firm connection. The slider 31 is connected to the guide rail 3 by a ball screw pair, which enables the slider 31 to achieve high-precision linear motion.

[0067] The drive cylinder 4 is a single-axis cylinder, model SC80-200, with a cylinder diameter of 80mm and a stroke of 200mm, used to drive the slider 31 to move on the guide rail 3. The drive cylinder 4 is fixed to the mounting bracket 1 by a mounting bracket made of 304 stainless steel, manufactured through bending and welding processes to ensure its strength and stability. The piston rod of the drive cylinder 4 is connected to the slider 31 by a connecting block made of aluminum alloy, which is connected to the piston rod and slider 31 by a pin connection to ensure the reliability of motion transmission.

[0068] The guide rail 3 and slider 31 structure on the mounting bracket 1, along with the drive cylinder 4 that drives the slider 31, allow the clamping member 2 to be flexibly adjusted within a certain range. When dealing with panels of different sizes, shapes, or layouts, the drive cylinder 4 can push the slider 31, enabling the clamping member 2 to accurately clamp the key parts of the panel, improving the versatility and adaptability of the fixture. For example, when producing various models of electronic device panels, even if the corner positions or dimensions of the panels differ, reliable clamping can be achieved by adjusting the position of the clamping member 2, reducing the need to change fixtures due to panel differences and improving production efficiency. For panels with irregular shapes or special layouts, such as panels with protrusions, grooves, or irregular edges, the position and angle of the clamping member 2 can be flexibly adjusted to better adapt to the characteristics of the panel, ensuring the stability and safety of the panel during handling. This flexibility allows the fixture to be applied to a wider range of panel production fields, meeting diverse production needs.

[0069] Example 5

[0070] See Figures 1-6 This embodiment provides a handling device, including a robotic arm, on which an automatic panel gripper as described above is provided.

[0071] In this embodiment, the automatic panel gripper is equipped with a photoelectric sensor, which is positioned facing the gripper 2 and is electrically connected to the control system of the robotic arm.

[0072] In practice, this robotic arm uses an industrial-grade six-axis robotic arm with a repeatability of ±0.05mm. The joints of the robotic arm are driven by high-precision reducers and servo motors, enabling fast and precise motion control and ensuring that the gripper can be accurately moved to the designated position during the handling process.

[0073] The connecting flange 11 of the mounting bracket 1 has a diameter of 300 mm and a thickness of 35 mm, and has 12 mounting holes 110 for connecting to the robotic arm.

[0074] A photoelectric sensor, model E3Z-L61, is installed near each gripper 2 of the fixture, featuring high sensitivity and fast response. The photoelectric sensor is fixed to the fixture via a custom-designed aluminum alloy bracket, with the installation angle precisely adjusted to ensure accurate detection of the working status of the gripper 2. The sensor's sensing area covers the slot 211 of the gripper 21, enabling timely detection of light changes and transmission of signals to the robotic arm's control system when a panel is correctly gripped or when an abnormality occurs.

[0075] During the work process:

[0076] The robotic arm, carrying a gripper, moves above the panel storage area and activates the vision recognition system to quickly locate the panel.

[0077] The robotic arm controls the gripper to descend based on visual recognition results, aligning the gripper 21 with the edge of the panel. A dual-axis cylinder drives the gripper 21 to close, and a pressure sensor (accuracy ±5N) monitors the clamping force, stopping the action when it reaches 3000N. During this process, a photoelectric sensor monitors the contact between the gripper 21 and the panel in real time. If an abnormal change in light is detected, such as the panel not being fully inserted into the slot 211 or misalignment causing light obstruction unlike normal clamping, a signal is immediately transmitted to the robotic arm control system. The control system then pauses the clamping action and makes adjustments to ensure the panel is accurately and reliably clamped.

[0078] The robotic arm moves the panel according to a preset path and speed. Upon reaching the target position, the dual-axis cylinder reverses airflow to open the gripper 21 and place the panel. During the movement, photoelectric sensors continuously monitor for any displacement or loosening of the panel. If any abnormality is detected, the robotic arm control system immediately stops its movement and issues an alarm to ensure safe handling. After the movement is completed, the robotic arm returns to the panel storage area to prepare for the next movement.

[0079] Example 6

[0080] See Figures 1-6 This embodiment provides a method for transporting a panel, which is implemented based on the transport device described above.

[0081] The transport process is as follows:

[0082] First, the handling device is started, and the robotic arm performs a self-check program to ensure smooth movement of each joint, normal sensor data, and stable communication with the automatic gripper on the panel. Then, the robotic arm is connected to and secured to the furniture.

[0083] The robotic arm moves the gripper above the panel storage area, activating the vision recognition system to quickly and accurately identify the position, size, shape, and orientation of the panels.

[0084] Based on visual recognition results, the robotic arm precisely controls the gripper to descend, aligning the slot 211 of the gripper 21 with the edge of the panel. Once the gripper 21 reaches the appropriate position, the drive unit 22 (such as a dual-axis cylinder) is activated, rapidly increasing the air pressure to the set value of 0.8 MPa. The piston rod then pushes the gripper 21 to close. During the gripping process, a pressure sensor monitors the gripping force of the gripper 21 in real time, ensuring the panel is reliably gripped and not damaged by excessive force. Simultaneously, a photoelectric sensor on the gripper continuously monitors the contact between the gripper 21 and the panel. If an abnormal light change is detected, such as the panel not being fully inserted into the slot 211 or a misalignment causing light obstruction different from normal gripping, a signal is immediately transmitted to the robotic arm control system. The control system then pauses the gripping action and makes fine adjustments to ensure accurate panel gripping.

[0085] The robotic arm moves the fixture holding the panel to the target processing or assembly position according to the preset optimal handling path and speed.

[0086] Upon reaching the target position, the drive unit 22 reverses airflow, and the piston rod drives the gripper 21 to open, releasing the panel with a placement accuracy of ±0.08mm, meeting the precision requirements of subsequent processing. The robotic arm quickly returns to the panel storage area, ready for the next handling operation.
